Help me choose: Mobile broadband

Unlike wireless cards that require WiFi routers, local networks and hotspots for internet access, cellular mobile broadband provides wireless internet access directly through cellular phone networks at average download speeds up to 1.4 Mbps* or about as fast as a wired broadband connection. Cellular mobile broadband is designed to connect anywhere within your carrier’s broadband coverage area; generally, this means the same places you can make a cell phone call with the same limitations.*
